SAIT LTD

PROJECTS

Here we describe several projects we currently work on. The results of some of them will hopefully become standard products. Others are interesting because of complexity or application.

MiniSAR

2021

We create a demonstrator of the advanced phase array technology for the synthetic aperture radars. It will be installed on the ISS. Main features and performance

Digital beamforming

C-band

Antenna size 2.5x1.25 m (determined by ISS limitations)

Baseline stripmap mode performance

Bandwidth up to 120 MHz

Ground range accessibility 200 km (incidence angles 17 - 40 deg)

Range swath 12 - 20 km

Resolution (2 - 4)/1.5 m (range/az)

NESZ < -20 dB (1 look)

Ambiguities < -20 dB

Various ScanSAR modes

Weight 70 kg

Broadband Communication System User Terminal

Q3'2018

Broadband Communication System User Terminal (BCS-UT) will be installed on the ISS SM "Zvezda" and provide near permanent connection of the ISS to the ground control through the GEO relay satellites "Luch".

Transmitter for the Moon spacecraft

2019-2023

SAIT will provide X-band transmitters for the Moon landers Luna-25 (Luna-Glob) and Luna-27, and for the Moon orbiter Luna-26.All transmitters will use innovative LDPC FEC. The orbiter transmitter will use 8PSK modulation for better utilization of the scarce X-band frequency allocation.
